I-API SPEC 7-1 Drill Pipe China Factory
I-Drill Pipe iyishubhu elisindayo, elingenamthungo lingakwazi ukuzungezisa ucezu lokubhoboza futhi lijikeleze uketshezi lokumba. Ivumela uketshezi lokumba ukuthi lumpontshwe ngebhithi bese lusekela i-annulus. Ipayipi lingaphansi kwe-axial tension, i-torque ephezulu kakhulu kanye nokucindezela okukhulu kwangaphakathi. Ipayipi lokubhoboza ipayipi lensimbi eliqinile elisetshenziswa emisebenzini yokumba, amazinga ku-API 5DP kanye ne-API SPEC 7-1.

1- Amakepisi epulasitiki axhunywe ezinhlangothini zombili zamapayipi
2- Kufanele kugwenywe ibhande lensimbi kanye nokulimala kwezokuthutha
3- Izimpawu ezihlanganisiwe kufanele zifane futhi zingaguquki
4- Inqwaba efanayo (inqwaba) yepayipi lensimbi kufanele ivele esithandweni esifanayo.
5- Ipayipi lensimbi linenombolo efanayo yesithando somlilo, izinga elifanayo lensimbi, imininingwane efanayo.
Sinikeza amamaki ahlukene e-API 5DP Drill Pipe, etholakala kubakhiqizi bamapayipi okubhoboza abangochwepheshe abavela e-China, ububanzi bokunikezela njengoba bungezansi:
Izinga kanye namaBanga
I-1-API 5DP Grade DZ50,
2-General Grade of Drill Pipe API 5DP Grade E75,
3-General Grade of Drill Pipe API 5DP Grade R780,
4-Medium ibanga eliphezulu le-Drill Pipe API 5DP Grade X95,
5-High grade Drill Pipe API 5DP Grade G105,
6-High grade Drill Pipe API 5DP Grade S135
Ipayipi lokubhoboza le-API 5DP lilandela ngemuva ngentambo yesikulufu yokuxhuma i-rig yokumba etholakala ngaphansi kwempahla yokumba engaphezulu kanye nemishini yokugaya noma ithuluzi lokuphuma elingaphansi. Inhloso ukubhoboza udaka lokubhoboza olulethwe ku-drill bit, nokubhoboza ngokukhuphuka, ukwehlisa noma ukuzungezisa izindlela zokuphuma phansi. Ipayipi lokubhoboza kufanele likwazi ukumelana nokucindezela okukhulu kwangaphandle, ukusonteka, ukugoba nokudlidliza. Enqubweni yokucwenga izimayini kanye nowoyela negesi, ipayipi lokubhoboza lingasetshenziswa izikhathi eziningi.
①Injani inkampani yakho?
Omunye wabakhiqizi nabahlinzeki abahamba phambili abagxile emikhiqizweni yamapayipi okubhola eShayina, ikakhulukazi abahlinzeka ngamapayipi okubhola ahlanganisa ipayipi lokubhoboza uwoyela, ipayipi lokubhoboza umthombo wamanzi, ipayipi lokubhoboza eliyisicaba, ipayipi lokubhola le-geological kanye nepayipi lokubhoboza elingambi. Ngaphandle kwamapayipi okubhoboza siyakwazi futhi ukuhlinzeka ngezinsiza ezahlukene zamapayipi, amajoyinti okubhoboza, izifakelo zamapayipi ensimbi, amavalvu njll. kuhlanganisa ukuthengisa kwethu okukodwa. Ukuthengisa okudidiyelwe nesevisi kuqinisekisa amakhasimende anezidingo ezihlukahlukene ukufinyelela okulula kokuphathwa kokuthenga.
②Ungaqinisekisa kanjani ikhwalithi yemikhiqizo?
Sesisungule uhlelo lokuphatha ikhwalithi ethuthukile emhlabeni wonke, zonke izixhumanisi ezisuka ezintweni ezingavuthiwe ziye emkhiqizweni wokugcina sinokuhlolwa kwekhwalithi okuqinile; Siyiqeda ngokuqinile imikhiqizo engafanelekile egelezela emakethe. Ngesikhathi esifanayo, sizohlinzeka ngesiqinisekiso sesevisi sokulandelela esidingekayo.
③Singakwazi ukuthola umkhiqizo isikhathi eside kangakanani ngemva kokuthenga?
Ekuthengweni komkhiqizo zingakapheli izinsuku zokusebenza eziyi-7, Sizohlela ukulethwa kwefekthri ngokushesha ngangokunokwenzeka.
